Surface Mount Technology – SMT Explained
The technique of directly attaching electronic components to the surface of a printed circuit board is referred to as SMT. As the leads are placed into the PCB using the through-hole approach, a problem will arise if the leads are not properly fitted, slowing down the production pace. All electrical items require more functionality
